Hey Allen, Live plumbing pics!

Ok, some explanation on the plumbing conglomeration in the photo. I’ll start with the pump. The suction hose which is the lowers hose on the tractor is currently coming from the supply tank in the left leg of the loader (see picture of left side). There is a quick coupler in it and on the bottom of the supply tank to facilitate taking the loader off the tractor and using the on-board supply tank instead. The hose that is on top of the belt pulley is the return from the power steering unit above the gas tank and the proportioning valve (small hose on the rear) located behind the oil filter. This is Tee’d into the suction line back to the pump.

The power steering pressure is taped off the upper left port of the valve and the center lower port of the valve has a quick coupler that goes either to the loader or the pressure side of the valve spool located just behind the belt pulley. Between the ½” quick coupler and the valve spool on the tractor is a pressure relief valve for the valve spool. The valve spool return is plumbed into a fitting on the left had side of the tractor back into the on board supply tank. The hose just behind the oil filter is the pressure side coming from the pump.

Probably sounds complicated and confusing so if you have any questions post back. I won’t be on much on Saturday, but will try to get back Saturday night.

It never ceases to amaze me how helpful you guys are! First Bob Frey, out of the kindness of his heart, scans pages and pages of an oil-flow schematic for me and now you take the time to take all these pictures & give a blow by blow breakdown! Boy, do I appreciate you guys’ efforts!! Hope I can repay you fellas some way, some day.

Took me a minute to figure out why your dad had plumbed that proprietary valve to the exhaust, then after I study the picture for awhile, it dawns on me that the valve is a 4-port valve....duh, okay! :>)

Boy! That looks like one sweet old hard workin' tractor; that's the nicest kind. If that pump will handle a heavy DUAL loader, it should darn sure handle my little F-11.

Looks good Pard,

Allan

Never thought of that, but you're probably right; those things squeeze 'er down to what? 1/4", 3/8" or some such amount?

I've decided to go the easy route and just plumb back to that loader tank 'cause it already has all the inlets I need for exhaust; the valves & pressure regulator are all enclosed and I'm not going to be rigging for a remote cylinder anyway.

The only thing I have to worry about is the proprietary flow to the power steering and that should go fairly well, I would think.

Thanks again,

Allan

I was thinking yesterday, if I pull the PTO pump and the belly pump drive, I should be getting two for the price of one, right?

I mean, right now the thing is pulling two hydraulic pumps. That belly pump has to take a certain amount of power away from the engine, doesn't it?

Allan

You are correct, the belly pump will take a bit of power, but I wouldn't think much unless it was under load. Then again if you don't need it, might as well unhook it.
